Figure 12: Alternating Read Cycle
For auto-increment reads the address register will be incremented automatically and subsequent data bytes can be
read from successive registers, without providing a second RAB.
Figure 13: Auto-increment Read Cycle
When the auto-increment mode is enabled, the Address Register will continue incrementing for each read cycle.
When the content of the Address Register reaches 4Fh, it will wrap around and start from 00h again. The auto
increment sequence can be terminated by either a “STOP” or “RESTART” condition. The read operation can be
terminated with a “STOP” condition.
Figure 13
shows an auto-increment read cycle terminated by a STOP or
RESTART condition.
